Abstract

The invention provides a ferromagnetic resonance probe. The ferromagnetic resonance probe comprises a planar waveguide and further comprises a base and a ballasting assembly; the planar waveguide is arranged on the base; the ballasting assembly is arranged on the base and provided with a bearing platform used for bearing a to-be-detected sample; and the bearing platform and the planar waveguide are arranged oppositely and movably so as to press the to-be-detected sample on the planar waveguide. According to the ferromagnetic resonance probe, the problem that as for a ferromagnetic resonance probe in the prior art, the situation that the to-be-detected sample is inclined to the planar waveguide is difficult to avoid in the detection process is solved; and a high-thermal-conductivity channelis established between the to-be-detected sample and the base, and fast and accurate control over the sample temperature is achieved.

Description

technical field [0001] The invention relates to the field of ferromagnetic resonance, in particular to a ferromagnetic resonance probe. Background technique [0002] The typical design schematic diagram of broadband ferromagnetic resonance under the existing parallel magnetic field is as follows: Figure 1 to Figure 3 shown. The basic components are back ground plane waveguide 1, high frequency connector 2 and electromagnet 3. The backside ground plane waveguide generates an RF field to drive and maintain the small-angle precession of the sample 4 magnetic moment. Since ferromagnetic resonance requires in principle that the magnetic field generated by microwaves must be perpendicular to the external magnetic field, the waveguide below sample 4 must be parallel to the external magnetic field; an electromagnet usually has a magnetic pole gap of several inches, and in order to achieve a higher magnetic field, further reduction is required. The gap is small, so the U-shaped pl...
